Hammer used in attack on two women in SF

San Francisco police have launched a special task force to track down the person who attacked two women in the Sunset District Thursday night.

Police canvassed the neighborhood Friday. They say the attacker used a hammer and knife. The brutal attack has shocked the neighborhood.

"This is amazing," one David Smith told ABC7. "These things don't happen out here that often." Smith runs a barber shop around the corner from the scene of the crime. He says one of the victims is a fellow business owner who owns four restaurants and a bakery in the area.

Police say the first victim, a 76-year-old woman, had just arrived at home when the attack happened. Investigators believe the weapons used included a knife and a hammer. During the attack, a second woman arrived at the home to deliver food. She saw what was happening and then she too was attacked. She ran into a nearby restaurant to call 911.

A team of investigators is scouring the area, but they only have a basic description of a suspect.

Neighbors describe the first victim as someone well known and respected, especially since she is a local business owner.

"I think many people know that they own some restaurants over there, and many of them only take cash, so it probably would be a reason," neighbor Cheryl Guan said.

Police are not saying this was a targeted attack, but they do say the first victim has a daily routine.

"We would hate to think that she was targeted specifically, but she does have, we believe now, a pattern that she does every day," Biel explained.

According to public records, the woman who lives in the house police are focusing their investigation on is named Rose Chung, a woman described by neighbors as very active in the neighborhood and very active politically as well.
